Why are there so many buttons if none of them do anything? There aren't even options available when the music is BLASTED at maximum volume the moment you start the game. The upgrading system from the 15 minutes that I played didn't feel like progression at all. I didn't even know what any of them did or what I was supposed to upgrade besides health, but that is the default option tbh. In the arena itself there isn't really much to do besides spam infinite dodge and hope you do enough dmg before your "HP" runs out without actually taking any damage.
The style was interesting but there wasn't much substance.
